Scope

<!-- NEW! -->IEC 62149-4:2022 is available as <a href="https://webstore.iec.ch/publication/81017">IEC 62149-4:2022 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 62149-4:2022 defines performance specifications for 1 300 nm fibre optic transceiver modules used for the ISO/IEC/IEEE 8802-3 Gigabit Ethernet application. This document contains definitions for product performance requirements as well as a series of tests and measurements, for which clearly defined conditions, severities and pass/fail criteria are provided. The tests are intended to be run on a "once-off" basis to prove any product’s ability to satisfy the performance standard’s requirements. A product that has been shown to meet all the requirements of a performance standard can be declared as complying with the performance standard but will then be controlled by a quality assurance/quality conformance program. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

- the normative references are updated;

- the condition "for short periods" in 4.1 is removed;

- the absolute limiting rating for soldering temperature in Table 1 is modified;

- the maximal optical output power (multimode fibre) in Table 4 is increased from −3,5 dBm to −3 dBm, to align value with the referenced document;

- a note is added to Table 7 to clarify that out-of-specification products are not allowed to pass the performance tests.
